Fortunately, however, the fog speedily lifted. The vessels closed up together, and, in two hours after starting, arrived off the entrances to the channels. Pisani anchored until daylight appeared, and nearly five thousand men were then landed on the Brondolo's shore, easily driving back the small detachment placed there. But the alarm was soon given, and the Genoese poured out in such overwhelming force that the Venetians were driven in disorder to their boats, leaving behind them six hundred killed, drowned, or prisoners.
But Pisani had not supposed that he would be able to hold his position in front of the whole Genoese force, and he had succeeded in his main object. While the fighting had been going on on shore, a party of sailors had managed to moor a great ship, laden with stones, across the channel. As soon as the Genoese had driven the Venetians to their boats, they took possession of this vessel, and, finding that she was aground, they set her on fire, thus unconsciously aiding Pisani's object, for when she had burned to the water's edge she sank.
Barberigo, with his light galleys, now arrived upon the spot, and emptied their loads of stone into the passage around the wreck. The Genoese kept up a heavy fire with their artillery, many of the galleys were sunk, and numbers of the Venetians drowned, or killed by the shot.
Nevertheless, they worked on unflinchingly. As soon as the pile of stones had risen sufficiently for the men to stand upon them, waist deep, they took their places upon it, and packed in order the stones that their comrades handed them, and fixed heavy chains binding the whole together.
The work was terribly severe. The cold was bitter. The men were badly fed, and most of them altogether unaccustomed to hardships. In addition to the fire from the enemy's guns, they were exposed to a rain of arrows, and at the end of two days and nights they were utterly worn out and exhausted, and protested that they could do no more. Pisani, who had himself laboured among them in the thickest of the danger, strove to keep up their spirits by pointing out the importance of their work, and requested the doge to swear on his sword that, old as he was, he would never return to Venice unless Chioggia was conquered.
The doge took the oath, and for the moment the murmuring ceased; and, on the night of the 24th, the channel of Chioggia was entirely choked from shore to shore. On that day, Corbaro succeeded in sinking two hulks in the passage of Brondolo. Doria, who had hitherto believed that the Venetians would attempt nothing serious, now perceived for the first time the object of Pisani, and despatched fourteen great galleys to crush Corbaro, who had with him but four vessels. Pisani at once sailed to his assistance, with ten more ships, and the passage was now so narrow that the Genoese did not venture to attack, and Corbaro completed the operation of blocking up the Brondolo passage. The next day the Canal of Lombardy was similarly blocked; and thus, on the fourth day after leaving Venice, Pisani had accomplished his object, and had shut out the Genoese galleys from the sea.
But the work had been terrible, and the losses great. The soldiers were on half rations. The cold was piercing. They were engaged night and day with the enemy, and were continually wet through, and the labour was tremendous.
A fort had already been begun on the southern shore of the port of Brondolo, facing the convent, which Doria had transformed into a citadel. The new work was christened the Lova, and the heaviest guns in the Venetian arsenal were planted there. One of these, named the Trevisan, discharged stones of a hundred and ninety-five pounds in weight, and the Victory was little smaller. But the science of artillery was then in its youth, and these guns could only be discharged once in twenty-four hours.
But, on the 29th, the Venetians could do no more, and officers, soldiers, and sailors united in the demand that they should return to Venice. Even Pisani felt that the enterprise was beyond him, and that his men, exhausted by cold, hunger, and their incessant exertions, could no longer resist the overwhelming odds brought against him. Still, he maintained a brave front, and once again his cheery words, and unfeigned good temper, and the example set them by the aged doge, had their effect; but the soldiers required a pledge that, if Zeno should not be signalled in sight by New Year's Day, he would raise the siege. If Pisani and the doge would pledge themselves to this, the people agreed to maintain the struggle for the intervening forty-eight hours.
The pledge was given, and the fight continued. Thus, the fate of Venice hung in the balance. If Zeno arrived, not only would she be saved, but she had it in her power to inflict upon Genoa a terrible blow. Should Zeno still tarry, not only would the siege be raised, and the Genoese be at liberty to remove the dams which the Venetians had placed, at such a cost of suffering and blood; but there would be nothing left for Venice but to accept the terms, however onerous, her triumphant foes might dictate, terms which would certainly strip her of all her possessions, and probably involve even her independence.
